How do you calculate the surface area of a sieve?

Answer 1

To calculate the surface area of a sieve, you need to assess its geometric shape. If the sieve is cylindrical, use the formula for the surface area of a cylinder: (SA = 2\pi r(h + r)), where (r) is the radius and (h) is the height. For a flat sieve, measure the diameter and use the formula for the area of a circle: (A = \pi r^2). Additionally, consider any mesh or perforated sections that might reduce the effective surface area.
